For testing the structural bonding of concrete, the specimen consists of three concrete cubes bonded in line which are then exposed to an environmental regime prior to being subjected to a compressive shear force applied in the plane of the bond line. For testing the structural bonding of steel, two steel plates are bonded together and subjected to a cleavage force applied by the insertion of a wedge. The stressed specimen is then exposed to an environmental regime during which measurements are taken. 4 Equipment 4.1 Concrete to concrete composites (see Figures 1a) and 1b) 4.1.1Steel mould for casting 100 mm × 100 mm × 100 mm concrete cubes. 4.1.2Jig to ensure accurate alignment when bonding the 100 mm × 100 mm × 100 mm cubes. 4.1.3Steel mould 100 mm × 100 mm × 302 mm for casting fresh concrete to hardened concrete specimens. 4.1.4Compression testing machine conforming to EN 12390-4 capable of testing the bonded specimens conforming to 6.2.1 and 6.2.2 in compressive shear. 4.1.5Test rig support to align the bonded cube assembly securely in the testing machine whilst the compressive shearing force is applied parallel to the planes of the bonds and distributed evenly between them, as depicted in Figures 1a) and 1b).

The thermal cycling regime is depicted in Figure 3. After 15 min initial cooling from 20 °C, the cycle starts from 25 °C according to the detail given in Figure 3. Each thermal cycle consists of a cooling phase over 6 h in air at a temperature of (- 25 ± 2) °C followed by a heating phase over 6 h in air at a temperature of (+ 55 ± 2) °C. The cooling and the heating shall take place at a rate of 3 °C/min. One cycle lasts for 12 h and comprises the following stages : 333 min air storage at T = (- 25 ± 2) °C ; 27 min heating in air to T = (+ 55 ± 2) °C ; 333 min air storage at T = (+ 55 ± 2) °C ; 27 min cooling in air to T = (- 25 ± 2) °C. During any interruption of the cycling the specimen shall be stored at standard climate conditions (21 ± 2) °C/(60 ± 10) % relative humidity). The complete thermal cycling regime shall consist of 50 cycles. 5.2 Warm-moist environment The warm-moist environmental regime shall consist of six months exposure to an environment maintained at (+ 40 ± 2) °C, (95 ± 5) % relative humidity). During any interruption to the regime the specimen shall be stored at standard climate conditions (21 ± 2) °C/(60 ±10) % relative humidity). 6 Preparation of test specimens 6.1 General For applications involving bonded plate reinforcement six specimens of hardened concrete to hardened concrete and six specimens of steel-to-steel shall be produced for testing associated with each environmental regime. Licensed Copy: sheffieldun sheffieldun, na, Mon Oct 30 05:45:11 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 13733:2002 (E) 6 For applications involving bonded mortar or concrete six specimens of either hardened concrete to hardened concrete or fresh concrete to hardened concrete shall be produced for testing associated with each environmental regime. For each environmental regime three specimens shall be tested. A further three specimens shall be maintained at standard climate conditions (21 ± 2) °C, (60 ± 10) % relative humidity) for control purposes. 6.2 Concrete to concrete composites 6.2.1 Production of the hardened concrete to hardened concrete specimens Concrete cubes of dimensions 100 mm × 100 mm × 100 mm shall be cast and cured in accordance with EN 1766. On one cube, two of the formed faces to be bonded and on two cubes, the formed face to be bonded, shall be gritblasted in accordance with the requirements of EN 1766. Immediately prior to bonding these gritblasted surfaces shall be vacuumed to remove any dust. Mix the components of the adhesive to be tested and apply an even layer approximately 1mm thick to each of the prepared concrete surfaces in accordance with the manufacturers instructions. Bond the three cubes together to produce a specimen with a bond line approximately 1mm thick as shown in Figure 1. It is necessary to use a jig to ensure accurate alignment of adherents. Allow the adhesive to cure for at least 7 days at (+ 21 ± 2) °C, (60 ± 10) % relative humidity. 6.2.2 Production of the fresh concrete to hardened concrete specimens Concrete cubes of dimensions 100 mm × 100 mm × 100 mm shall be cast and cured in accordance with EN 1766. On two of the cubes, the cast face to be bonded shall be gritblasted in accordance with the requirements of EN 1766. Immediately prior to bonding this gritblasted surface shall be vacuumed to remove any dust. The components of the adhesive shall be mixed and an even layer approximately 1 mm thick applied to the prepared concrete surfaces in accordance with the manufacturers instructions. Place the two cubes at a separation of (102 ± 0,2) mm in the 100 mm × 100 mm × 302 mm mould. The concrete shall be poured into the central 100 mm × 100 mm × 100 mm volume and carefully compacted by hand in accordance with EN 1766. The complete assembly shall be cured for at least 28 days at (+ 21 ± 2) °C, (60 ± 10) % relative humidity. 6.3 Production of steel-to-steel composite specimens Degrease one side of each steel plate using a suitable degreasing agent and then gritblast to grade Sa 2.5 according to ISO 8501-1. The gritblasted surface shall then be vacuumed to remove any dust. Glue PVC tape (12,5 mm wide) on one end of the plate so that the wedge can be inserted there (see Figure 2). Mix the components of the adhesive and apply an even layer approximately 0,5 mm thick to each of the prepared steel surfaces in accordance with the manufacturers instructions. Bond the steel plates together in a suitable jig (for example, see Figure 4) in order to achieve a glueline thickness of (0,65 ± 0,05) mm. Allow the adhesive to cure for at least seven days at (+ 21 ± 2) °C, (60 ± 10) % relative humidity, before inserting the wedge at a rate of 50 mm/min to its full depth of 25 mm in a suitable compression testing machine. 7 Test procedures 7.1 Testing of the concrete-to-concrete specimens After the specimens have undergone the appropriate environmental regime, they shall be conditioned for 24 h at (21 ± 2) °C and (60 ± 10) % relative humidity. The test and control specimens shall then be tested in shear as Licensed Copy: sheffieldun sheffieldun, na, Mon Oct 30 05:45:11 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 13733:2002 (E) 7 shown in Figures 1a) and
